DEVICE FOR DETECTING LOW-PRESSURE STATE OF TIRE |
摘要 |
Provided is a device for detecting a low-pressure state of a predetermined tire, comprising an index value calculation unit, a resonance frequency calculation unit and a low-pressure detection unit. The index value calculation unit calculates a low-pressure index value from wheel speed information of front and rear tires, the low-pressure index value being obtained by comparing rotation speeds of the front and rear tires. The resonance frequency calculation unit calculates a resonance frequency from wheel speed information of a tire. The low-pressure detection unit eliminates an influence of an imposed load on a vehicle and detects the low-pressure state of the predetermined tire based on: a predetermined parameter that indicates a linear relationship between the resonance frequency and the low-pressure index value under a low-pressure condition of the predetermined tire; the low-pressure index value thus calculated; and the resonance frequency thus calculated. |
